This won't answer your question (not sure why missing doesn't work 
anymore), but you could wait for the replacement and then run "btrfs 
replace start 1 /dev/sdd /mnt", where 1 is the devid of the missing 
drive (dmesg will tell you) and /dev/sdd is the new drive. This way, the 
drive will keep its devid, which may be useful if the ids are used to 
identify the drives (mirror will still have id 1 as first drive and id 2 
as second drive as opposed to 2 = first and 3 = second).
